Columbia County, FL Outdoor Lighting: Light Trespass & Shielding (2026)

Section 4.2.20.7, titled Glare, is one of the performance standards in article 4.2 of the Land Development Regulations that every use and activity in unincorporated Columbia County must meet regardless of zoning district. The rule is short and direct: there shall be no direct glare visible from any residential district caused by unshielded floodlights or other sources of high intensity lighting. The provision targets the light source itself rather than a numeric lumen threshold, meaning a commercial, industrial, or agricultural operation next to housing has to shield or aim floodlights and similar high-intensity fixtures so their direct glare does not reach into a residential district, rather than simply staying under a foot-candle limit.

This performance standard sits in the same numbered section as the county's other nuisance controls, including noise, odor, and fumes, all measured at the property line except within the I-Industrial district, where the standard applies at the district boundary instead of individual lot lines. The lighting rule for automotive service stations elsewhere in the code echoes the same principle: section 4.2.6.2 separately requires that lights at a gas station be designed and arranged so no source of light is visible from any residential district, showing the county applies the unshielded-light concept across multiple use types.

Because section 4.2.20.7 is a performance standard rather than a permit condition, it can be enforced against an existing use whenever a resident complains that a floodlight is casting direct glare onto their property, not just at the time a new use is approved.
